AXLE.

SPECIFICATION forming part of Letters Patent No. 453,840, dated June 9,1891.

Application led October 12, 1888. Renewed April 16, 1891. Serial No.389,132. (No model.)

To @ZZ whom it' may concern.-

Be it known that I, BUsHRoD Il. KEMBLE, a citizen of the United States,formerly residing in the city and county of Philadelphia, State ofPennsylvania, now residing in the cityand county of Camden, State of NewJ ersey, have invented a newand usefullmprovement in Axles, whichimprovement is fully set forth in the following` specilication andaccompanying` drawings.

My invention consists in constructing an axle with trusses, whereby thesame possesses great strength and durability, as will be hereinafterfully set forth.

It also consists in the combination of parts, as herein set forth andclaimed.

Figure 1 represents a partial side elevation and partial longitudinalsection of an axle embodying my invention. Fig. 2 represents a verticalsection on line af x, Fig. l.

Similar letters and numerals of reference denote corresponding parts inthe several tigures.

Referring to the drawings, A represents an axle of tubular form andconstructed of steel, said axle being formed in sections connected by acoupling l, from which depends a post or hanger 2, to whose lower end issecured an open piece or eye 3, the sides of which have threadedopenings to receive the innerends of the truss-rods B, the outer endswhereof are screwed or otherwise connected with collars 4, the latterbeing formed with plugs or necks 5, which enter the outer ends of thetubular or hollow axle A and are secured thereto. On the inner or lowerends of the truss-rods are nuts 0 7, which bear against opposite sidesof the eye or frame 3 and serve to tighten the connection of thetruss-rods with said frame, and consequently with the axle, it beingevident that the axle is braced by the truss-rods and the parts whichconnect said rods with the axle, so that the strength and durability ofthe axle'are increased. The

truss may be strained or tightened when required by properly rotatingthe nuts 6, which are accessible in the opening of the eye 3, the

nuts 7, which act as j ani-nuts, being also properly rotated. Each plugo1* neck 5 and collar 4 are integral with the journal orbearing portion8, on which the box revolves, whereby the journal is firmly connectedwith the axle, it being seen that the plug enters the axle, and thusalso strengthens the contiguousends of the same.

The nut 9, which confines the box, and consequently the wheel, on thejournal, is hollow, forming a lubricator, the same having a tubu larneck l0, which screws into the journal, the bore of said neck forming acommunication between the journal and the combined lubricator and nut.Interposed between the box and the flange 1l on the inner side of thenut is a split washer l2, which serves to prevent rattling of the partsin contact and takes up lostmotion thereof as the box and ange or nutwear away, in which case the nut is tightcned, thus compressing thewasher.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A hollow sectional axle with a coupling having a hanger thereon witheyes in its side walls, collars secured to said axle at its ends, andtruss -rods adj ustably secured to said hanger and collars, said partsbeing combined substantially as described.

2. An axle formed in sections and a coupling therefor and a hanger onsaid coupling having an eye, in combination with truss-rods secured tosaid section and eye and nuts at the inner ends of the truss rodsbearing against said eye, substantially as described.

3. A hollow axle and atri1ss-rod,in combination with a plug carrying ajournal and entering the axle, one end of the truss-rod being secured tosaid plug and the other end to a hanger secured to said axle,substantially as described.
